Yes it does. The issue is that if frost builds up, this blocks the cold air from circulating from the freezer to the refrigerator.How long has the refrigerator been on since defrosting?
This is a defrosting issue. The unit needs to defrost to remove the frost off of the coils. There is either a defective defrost heater, bi metal, or timer. Do you have a meter to check continuity and for voltage?
OK, there is air circulating into the refrigerator. You will have to give it about 3 hours before you notice cold air in the refrigerator.
The way it works is that the cold air is generated for the freezer. The freezer fan will then circulate that air up through the vent, then go down the refrigerator and through another vent back into the freezer. If frost builds up on the back wall, this will block that air flow and all of the cold air will settle in the freezer and not go into the refrigerator.
So like I said, the issue is either the heater, bi metal, or timer. A real quick check you can do to see what part is defective is remove the back wall, on the bottom of the coils you will see a metal part that has two wires going to either side of it. This is the heater. IF you remove this part and look at it, you can tell if it is defective. the heater is essentially a glass light bulb. IF it is defective, it will be black and look like a burned out bulb.
Can you send me the model number so I can tell you definitively how to remove them. Each model is different.
Here is a link to a site where you can order the part. Just follow the wires up to the top and the should go behind a panel where the fan motor is. There is a white plug that you can unplug to disconnect the wires. THis part also comes as an assembly with the bi-metal, so that will have to be removed as well.
